The table below details the different part numbers for IC1002. Note that this IC can either be an EPROM or a
MTP. An EPROM has a small window in its top to enable the IC to be erased by ultra-violet light. A MTP does
not have this window and normally works at 3.3V.

Note 2 - Second NVM Fitting
Some sets use a second NVM, designated IC1004 to store teletext page information and some audio data in the
case of Dolby Pro-logic models. Sets that have the second NVM fitted are:
66FW54H 76FW54H 66GF64H 76GF63H 76GF64H
The part number for this device is the same as IC1003.

These IC are not interchangeable.
Note 4 – IC801 Types
IC801 can be one of two types. It is either a 3120 or 3130, and they are not interchangeable. The part number
for the VDP3120C2 is RH-IX1688BMN2, the part number for the VDP3130Y is RH-IX1858BMZZ. The 3130 are
fitted in all HW models and some later FW and GF models.
Some patterning can occur when fitting later revisions of the VDP3120C2 to earlier chassis versions. In this
situation remove C824, which is connected from pin 33 of IC801 to ground.
